Originating from France, the solex became synonymous with lightweight and economical transportation.
The solex typically features a single-speed or occasionally a two-speed transmission, which allows the rider to control the speed of the vehicle by pedaling or engaging the engine. The engine is usually a two-stroke type, meaning it completes a full power cycle in two strokes of the piston. This simplicity in design facilitates easy maintenance and reduces mechanical complexities.
One of the distinctive features of the solex is its unique fuel delivery system. It employs a small, integrated fuel tank and a gravity-fed carburetor, supplying the engine with the proper air-fuel mixture and ensuring smooth combustion. This design choice contributes to its overall efficiency and convenience, as it eliminates the need for fuel pumps, fuel lines, and electric ignition systems.
The solex's lightweight construction, coupled with its practical design, offers an affordable and accessible mode of transportation. It gained popularity due to its ease of use, low maintenance requirements, and fuel efficiency. Although other brands of motorized bicycles exist, the term "solex" has become synonymous with this type of vehicle and conjures images of a simple, reliable, and economical mode of transportation.
The word "Solex" has its origin in the French language. It is a combination of two words: "Soleil" meaning "sun" and "Ex" meaning "out". Therefore, "Solex" roughly translates to "sun out" or "sunlight". The name "Solex" was chosen for a brand of motorized bicycles that were manufactured in France, popularly known for their models equipped with a small two-stroke engine. These bicycles were initially manufactured by Solex company, founded in the early 20th century. Over time, "Solex" became synonymous with motorized bicycles and was used generically to describe similar vehicles.
